In humans, the gene for curly hair (H) is incompletely dominant to the gene for straight hair (h). Individuals that are heterozygous (Hh) have wavy hair. Two wavy-haired heterozygous parents have a child. What is the likeliness that the child will have wavy hair?

The likeliness that the child that the two wavy-haired heterozygous parents will have will possess wavy hair is: 50%

Given the following:

Two parents that are heterozygous are: (Hh) x (Hh)

The cross between both parents will produce the following offspring as shown in the Punnett Square attached below:

Therefore, the likeliness that the child that the two wavy-haired heterozygous parents will have will possess wavy hair is: 50%

1/2 (50%) of the offspring will have wavy-hair

Explanation:

The question is describing a autosomal type of inheritance pattern, being the dominant trait curly hair (allele H), and the recessive (non-dominant) trait straight hair (allele h). There are three phenotypes one can obtain from this allele: HH ⇒ Curly hair, Hh ⇒ Wavy hair, and hh ⇒straight hair. We are informed that two wavy-haired heterozygous parents have a child, meaning that both parents present a genotype of Hh. To obtain the probability of type of offspring, it is necessary to perform a Punnet square:

             H      |      h

———————————

H    |     HH     |    Hh      

———————————

h    |     Hh       |   hh    

One can conclude that the amount of offspring with wavy-hair phenotype, will be 2/4 = 1/2 = 50%

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
